Inventory by Entity(PDF Version)
The inventory is made up of the transportation and communications centers, the field equipment, the vehicles, and other systems in the regional transportation system. In the National ITS Architectures, 'entities' are the subsystems and terminators that generally represent the systems in ITS. The following table sorts the inventory by National ITS Architecture entity. This sorts elements that perform similar functions together, so elements of a particular type can be easily identified.
